Husky 128LD trimmer

Background:
Only used 1 year, ran flawlessly for that year, until it fell off its wall hanger during a storm. It didn't run very well after that, discovered that the plug had cracked. New plug, never would start/run after that. Will not even start with starter fluid, won't even fire/putter, not a single ignition whatsoever.

What I've done:
Replaced spark plug, w/correct gap
Tested spark with spark tester, will arc over 3/4 inch
Replaced ignition module

Ideas?

Buy a new one?

All 2 strokes are is air/spark/fuel. If you're missing one of those things, you're gonna have a bad time...


Your spark looks good, doubt its' the air. Dump out all fuel, put in all fresh & make sure a line's not pinched, etc. Check your carb, may be flooding.

have you no value of anything? when your car needs spark plugs because its running poorly, do you just buy a new one?


OP- i have the same issue with my chainsaw. i took it apart and found that i had damaged the fuel feed to the carb. replaced and it runs like new.

It won't even fire with starter fluid directly in the cylinder though, the plug will be saturated with fuel after trying to start it for a few minutes. When I say it won't fire, I literally mean it won't ignite the mixture whatsoever.

The reason I replaced the ignition module is that I thought the spark wasn't timing correctly. I've also ensured I have the correct gap between the flywheel and the ignition module.

I like to tinker and learn... but yes, one could argue that would have been more efficient, as I've now spent $45 and time/hassle, which could have gone to a new trimmer.

We're talking about a $120 weed whacker not a $40,000 car.... Your comparison makes no sense.

He's already spent money searching for a fix and it still won't work. I'll fix something myself or pay to have it fixed if I know what is wrong and it makes economical sense. What's the point of continuing to throw more money into a broken weed whacker when a new one costs so little? By the time he figures out what is broken and fixes it he'll have spent as much as a new one costs.

You might have sheered the woodruff key on the flywheel when it fell. This will allow the flywheel to spin on the crank, making the timing so far off that it won't fire, even if you still have spark.

Also, check the throttle and choke. When it fell, it might have damaged the throttle cable, or bent the choke shaft (he he, he said choke shaft).

The flywheel appears to be solidly attached to the crankshaft, it also appears that the ignition and magnets on the flywheel come into contact just before TDC, however, there is a prominent "click" nowhere near TDC...

When you replaced the spark plug did u push the piston all the way down?
Check inside the cylinder if its not damaged? Maybe losing compression?
try putting in a bit of fuel in the carburetor?

I suspect the fall and the running problem are unrelated. If you leave premix in a carb for any length of time it will gum it up and it won't run right. You need to take the carb apart and clean it, or take it to a tool shop and let them do it. in the future, when you are done using it dump the gas out of the tank then run the engine until it dies, then try to start it again. When it won't start again you are ready to put it away.

Also, if its a newer tool it will have a fine mesh over the exhaust, it will get clogged and need cleaning.

Doesn't even run with starter fluid directly in cylinder, not even a sniff of ignition, also, fuel is wet on the plug normally. Strong spark.

So, spark isn't the problem, lack of fuel isn't the problem, appropriate mixture of air and fuel is.

Carb and exhaust, check them out.

Edit: A pool of starter fluid is not good either, it is intended to be a mist when it is used. Spraying starter fluid in the cyl then putting the spark plug in and pulling the cord is no good.
